Description

Technical Field

[0001] This utility model relates to the field of customized electric shock product integration technology, specifically a small high-voltage transformer with variable parameters. Background Technology

[0002] A high-voltage transformer is a device that converts low-voltage direct current into high-voltage direct current. It is currently widely used in televisions, monitors, radios, car ignition systems, stun guns, and other devices.

[0003] In different application scenarios, the specific form and function of the high-voltage pack vary. For example, in monitors and televisions, the high-voltage pack is used to generate anode high voltage to accelerate the electron beam to strike the fluorescent screen and generate an image. In the ignition system of automobiles and motorcycles, the high-voltage pack converts low-voltage electricity into high-voltage electricity to generate enough electric spark to ignite the fuel. In portable devices such as stun batons and stun grenades, the high-voltage pack is a small high-voltage pack. Because the high voltage is too small in space, it is easy to generate ionization, resulting in the large size of traditional high-voltage packs, which are difficult to apply to portable devices such as stun batons and stun grenades. Therefore, this utility model proposes a small high-voltage pack. Utility Model Content

[0004] The purpose of this invention is to provide a small high-voltage transformer with variable parameters, which solves the problem that traditional high-voltage transformers are large in size and difficult to apply to special application scenarios because ionization is easily generated when the high voltage is too small in space.

[0005] The technical solution of this utility model is:

[0006] A small, variable-parameter high-voltage pack includes: a housing, which can be designed as a cylindrical shell adapted to be used with an electric baton or stun gun; a battery located inside the housing and disposed near one end of the bottom surface of the housing, the battery being positioned offset from the central axis of the housing; a transformer disposed on the side wall of the housing, located on one side of the battery, for increasing the voltage; an adjustable mode circuit disposed on the other end of the bottom surface of the housing and connected to the battery and the transformer; and a voltage multiplier circuit module disposed on the side wall of the housing, opposite to the transformer, with the high-voltage output terminal of the voltage multiplier circuit module disposed near one end of the bottom surface of the housing, and the voltage multiplier circuit module being electrically connected to the transformer. The adjustable mode circuit and the voltage multiplier circuit module of this invention are designed separately. The adjustable mode circuit is installed at the bottom of the housing, and the voltage multiplier circuit module is installed on the side of the housing. The high-voltage output terminal is spaced relatively far from the adjustable mode circuit, reducing the overall space occupied. This design also solves the problem of spatial isolation between high and low voltage, preventing ionization. It addresses the issue that traditional high-voltage packs are bulky and unsuitable for special applications because ionization easily occurs when the high voltage is too small in space.

[0007] Furthermore, the high-voltage output terminal of the voltage multiplier circuit module is at least 20mm away from the adjustable mode circuit. This ensures that, under high-voltage conditions, the high-voltage output terminal of the voltage multiplier circuit module and the adjustable mode circuit maintain an appropriate distance, thereby reducing electrical short circuits or other safety risks. At the same time, it prevents electromagnetic interference between circuit modules and ensures the normal operation of the circuit.

[0008] Furthermore, the battery is a small 3.7V battery, which not only reduces the size but also provides a stable power supply to the control circuit inside the high-voltage pack, ensuring that the high-voltage pack can operate normally under various working conditions.

[0009] Furthermore, the battery is positioned off-center from the central axis of the housing.

[0010] Furthermore, the outer shell is configured as a cylinder adapted to be used with stun batons or stun grenades, with the cylindrical shell having a diameter of 16mm and a length of 30mm.

[0011] Furthermore, the transformer is a small-volume transformer with external dimensions of 12mm×10mm×6mm, which can achieve high-voltage conversion in a limited space, saving space and reducing the overall weight of the high-voltage pack.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model adopts a distributed design, selecting a small-volume 3.7V battery and a small-volume transformer. The adjustable mode circuit and the voltage multiplier circuit module are designed separately. The adjustable mode circuit is installed at the bottom of the shell, and the voltage multiplier circuit module is installed on the side of the shell. The high voltage output terminal is relatively far from the adjustable mode circuit. The overall layout reduces the space occupation and solves the spatial isolation between high voltage and low voltage to avoid ionization. Finally, the required high voltage parameters are output in a small space, which solves the problem that the traditional high voltage transformer is large in size because high voltage is prone to ionization when the space is too small.

[0014] The high-voltage transformer of this invention has a shell diameter of 16mm and a length of 30mm. While maintaining the same parameters as high-voltage transformers on the market (input 3.7V, output 11KV, 8mA), it is smaller in size and suitable for special application scenarios. Moreover, by adjusting the wires leading out from the adjustable circuit, the circuit operation mode can be changed, thereby realizing the adjustment of voltage, current and frequency, and the voltage can be adjusted from 6 to 11KV, further improving the applicability of the high-voltage transformer.

[0022] Example

[0023] like Figure 1 and Figure 2As shown in the figure, a small high-voltage package with variable parameters includes: a housing 5, a battery 1, a transformer 3, an adjustable mode circuit 2, and a voltage multiplier circuit module 4. The housing 5 is a cylindrical shell with an outer dimension of 16 mm in diameter and 30 mm in length. The battery 1 is located inside the housing 5 and is arranged near the bottom surface of one end of the housing 5. The position of the battery 1 deviates from the central axis position of the housing 5 and is used to provide an initial low-voltage current. The transformer 3 is arranged on the side wall of the housing 5, on one side of the battery 1, and is used to increase the voltage and convert the input low voltage into a high voltage. The adjustable mode circuit 2 is arranged on the bottom surface of the other end of the housing 5 and is connected to the battery 1 and the transformer 3. Therefore, in this embodiment, the battery 1 supplies power to the circuit through the adjustable mode circuit 2, and at the same time, it realizes voltage boost and voltage stabilization and then outputs to the transformer 3 to further increase the voltage. After the output of the transformer 3, it is given to the voltage multiplier circuit module 4 to achieve the final high-voltage output. The voltage multiplier circuit module 4 of this embodiment is arranged on the side wall of the housing 5, opposite to the transformer 3, and the high-voltage output end of the voltage multiplier circuit module 4 is arranged near the bottom surface of one end of the housing 5. The voltage multiplier circuit module 4 is electrically connected to the transformer 3 and is used to generate a high-voltage output. The overall layout reduces the space occupation, and at the same time solves the spatial isolation between high voltage and low voltage. Finally, it realizes the output of the required high-voltage parameters in a small space, and the whole electrical appliance is arranged inside the housing 5.

[0024] It should be noted that the adjustable mode circuit 2 in this embodiment can adopt a circuit in the prior art that can achieve adjustable output voltage and voltage boost, such as the patent with the publication number CN117765849A and the authorized patents with the authorized publication numbers CN217721028U and CN221886298U; as an alternative embodiment, this embodiment also provides an adjustable mode circuit 2 as shown in Figure 3 The adjustable mode circuit 2 includes a plurality of capacitors and a plurality of diodes. For the specific circuit connection, please refer to Figure 3 , Figure 3 In the figure, C represents a capacitor, D represents the diode number, the capacitor model: 1nF / 2KV, that is, 102 / 2KV, the capacitor package: 1206; the diode model: R4001F; the diode package: DO-214AC; by using the adjustable mode circuit 2 shown in Figure 3 to increase the voltage, and at the same time, by connecting the drawn wire to the corresponding adjustment IO pin, it is convenient for manual adjustment or adjustment by other controllers. The wire drawn from the adjustable circuit can change the circuit working mode, so as to realize the adjustment of voltage, current, and frequency, and achieve the output of multiple high-voltage parameters of a high-voltage package, which can increase the adaptability of the high-voltage package.

[0025] As shown in Figure 1 and Figure 2As shown, this utility model adopts a distributed design, selecting a small-volume 3.7V battery and a small-volume transformer. The adjustable mode circuit 2 and the voltage multiplier circuit module 4 are designed separately. In terms of installation position, the adjustable mode circuit 2 is installed at the bottom of the housing 5, and the voltage multiplier circuit module 4 is installed on the side of the housing 5. The high-voltage output terminal is more than 20mm away from the adjustable mode circuit. The overall layout reduces the space occupation and solves the spatial isolation between high voltage and low voltage. Finally, the required high-voltage parameters are completed in a small space. The wires leading out from the adjustable circuit can change the circuit working mode, thereby realizing the adjustment of voltage, current and frequency, and realizing the output of multiple high-voltage parameters of one high-voltage transformer.

[0026] The small-volume 3.7V battery used in this embodiment not only reduces the size but also provides a stable power supply to the control circuit inside the high-voltage transformer, ensuring that the high-voltage transformer can operate normally under various working conditions.

[0027] The high-voltage output terminal of the voltage multiplier circuit module 4 of this invention is at least 20mm away from the adjustable mode circuit 2. This ensures that, under high-voltage conditions, the high-voltage output terminal of the voltage multiplier circuit module 4 and the adjustable mode circuit 2 are at an appropriate distance, reducing electrical short circuits or other safety risks. At the same time, it prevents electromagnetic interference between circuit modules and ensures the normal operation of the circuit.

[0028] The small-volume transformer selected in this invention has an external dimension of 12mm×10mm×6mm, which can realize high-voltage conversion in a limited space, saving space and reducing the overall weight of the high-voltage transformer.

[0029] This embodiment uses a 3.7V battery for power supply to achieve an adjustable high voltage output of 6~11KV. The final result is a high voltage transformer with a diameter of 16mm and a length of 30mm, which is currently the smallest with the same parameters. By changing the circuit working mode, the voltage, current and frequency can be adjusted, and a small high voltage transformer with multiple high voltage parameters can be achieved. It can adapt to special applications and cover most application scenarios.

[0030] This embodiment adopts a distributed design, selects a small-volume 3.7V battery and a small-volume transformer, and designs the adjustable mode circuit 2 and voltage multiplier circuit module 4 separately. The installation process adopts a side-mounted method to reduce space occupation, while solving the spatial isolation between high voltage and low voltage, and finally realizing the output of the required high voltage parameters in a small space.

[0031] The above-disclosed embodiments are merely preferred embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
